To all whom it may concern:

Be it known that I, NATHAN FALLEK, a citizen of the United States ofAmerica, residing in the city and county of Denver and State ofColorado, have invented a new and useful Electrically0perated Single orVibratory Gong-Ringing Device, ofwhich the following is a specification.

My invention relates to improvements in automatic electrically operatedsingle or vibratory clapper apparatus for alarm gongs; and the objectsof my invention are: First, to provide an automatic electricallyoperating alarm bell or gong ringing and gong clapper apparatus forstreet railway cars, that will automatically and continuously ring thegong with a succession of vi.- bratory rings when a car is standingstill,

unless the motorman holds the crank handle against'the stop post of thecontroller, and which also will ring a single stroke ring of the alarmgong intermittently from the time the inotorman starts to turn on thecurrent until the car hasstarted and attained a fair rate of speed.Second, to provide an electric-ally-controlled automatically operatingalarm ringing and gong clapper apparatus, that will enable motormen tocontinuously sound either a vibratory or a single bell stroke alarmwhenever desired. And third, to provide an automatically operatingelectrically controlled alarm gong device that will continuously ring analarm whenever a motorman fails to hold the switch crank against thestop post of the controller or fails to remove the controller crank fromthe controller when he leaves the controller, and that willautomatically ring a single stroke at a plurality of predeterminedpoints of the circular movement of the controller crank when switchingthe current on or 05. the car. I attain these objects by the mechanismillustrated in the accompanying drawings, in which:

Figure 1, is a front elevation of a box or housing which incloses themagnet, armature, and circuit make and break device, forming part of theoperating mechanism of the improved electrically operated gong ringingapparatus, the cover for said box being removed. Fig. 2, is a sectionalview through the box, on the line 22 of Fig. 1. 3, is a plan view of acontroller box such as is commonly employed in conneceleinent of mypresent invention.

tion with electric street cars, showing a new ci'inducting ring andeasing therefor, which ring is provided with a plurality of contactswhich connect with a battery and magnet, and which are in position to beengaged successively by a contact on the controller crank. Fig. 4:, isan enlarged, perspective view of the non-conducting ring and itscontacts, showing the manner of connecting the contacts with each otherand with the i agnet, and also showing switches for cutting out any oneof the contacts. Fig. :3, is a vertical, sectional view through thecontact supporting ring and its housing. Fig. 6, is a longitudinalvertical sectional view through a fragment of the ring, showing themanner of securing the contacts in slots within the ring. Fig. 7, is aview in diagram illustrating the manner in which the controller crankengages the contacts, and the manner of connecting the various contacts,in circuit with a battery, and with magnet, which operates an armatureprovided with a gong striking hammer. And Fig. 8, is a similar view,showing an arrangement adapted for patrol wagons, ambulances, and thelike.

Similar characters of. reference refer to similar parts throughout theseveral views.

Referring to the drawings, the numeral 1, designates a box whichincloses a magnet, an armature, and a current make and break device,which features form the principal This box comprises a metal casing ofpreferably cast iron, brass, or steel, the back portion of which isprovided with feet 2,, which are provided with a screw receivingaperture, whereby the box may be secured by screws to any portion of thebody of a car or other vehicle or to a building where it is desired touse an alarm gong. The top portion of the box is provided with a cover3, which is rcmovably secured to it, preferably by screws 4. inside ofthe box I place a pair of powerful coil magnets 5 and 6, which I securein the box in any suitable manner. These magnets comprise round orhollow spools 7, in the axial aperture of which large blocks of solidmetal 9 and. 10 are placed, which extend through the spools. 6n the endof the block 10, an upwardly projecting lug 11 is formed, which providesa large strong magnetic pole when magnet-- ized. Adjacent to the core 9of the opponet.

site coil and spool, I place in the box a stem it may be turned into orout of the casing or shaft 12, which is pivotally mounted at its innerend in an adjustable plug 13, which is screwed into a threaded aperturein the back of the box, and at its outer end in a bracket 1a, which issecured to the outer portion of the adjacent side of the boX. A collar15 is secured to the stem 12, adjacent to its outer end, which bearsagainst the inner face of the bracket 14, and thewear caused by themovement of the stem is taken up by adjusting the plug 13. Upon the stem12 is formed a plate of metal, which constitutes the armature 16, andwhich extends in front of the magnet cores in position to be attractedby them when the coils are energized. The armature is thick and wide,and thus presents a large area to be acted upon by the magnets. The freeend of the armature is provided with a lug of metal 17, which projectsupward at right angles to the armature, and lies adjacent to andparallel with the upward projection 11, of the magnet core 10, when thearmature is engaged by the magnets, the projections 17 and 11 formingadditional metal, which increases the power and efliciency of the mag- Ablade spring 18, is secured at one end to the free end portion of thearmature, and its opposite end is engaged by an adjustable screw 19,which is threaded through the adjacent side of the casing and isprovided at its outer end with a slotted head to receive a screw driver,by which it may be adjusted, and with a check nut 17. This spring actsas a buffer cushion to the rearward stroke of the armature.

Upon the pivotal stem 12, is formed a lug 20, to which one end of acoiled spring 21 is connected, the opposite end of which spring issecured in an aperture formed inthe free end of an adjustable screw 22,which is threaded through the side of the casing, and is provided with aslotted head portion at its outer end, to receive a screw driver, bywhich it may be adjusted, and with check nuts 23 to lock it in adjustedposition. The spring 21 is arranged to hold the armature under aresilient tension away from the cores of the magnets. Adjacent to thearmature and magnets, I secure to the inside of the casing a circuitmake and break device, which comprises a pair of spring blades 24 and25, which are arranged opposite each other at short distance apart, andare provided on the inside of their outer ends with tarbon buttons 26and 27 respectively, which are suitably secured in sockets 28, on theends of the springs. The carbon terminal 26 is held in an adjusted rigidposition by an adjustable screw 29, which passes through a threadedsleeve 80, which is screwed through the shell of the casing, the screwbeing provided with a slotted head portion adapted to receive a screwdriver by which against the spring blade and with a check nut 31, bywhich it may be set in adjusted positions to hold the carbon terminal 26in the desired position relatively to the carbon terminal 27. The end ofthis screw is provided with a non-conducting tip 2-32. The carbonterminal 27 is arranged to bear with a slight resilient tension of itsspring blade a; inst the carbon button 26, thus maintaining a r silientcontact connection with the carbon contact point 26. The outer end ofthe pivotal stein projects beyond the cover 3, of the box 1, and one endof a gonostriking clapper 33 is attached to it, preferably by a pin 33,which passes through registering holes in clapper and in the stem. Theopposite end of the clapper is provided with hammer block 3%, which isslidably mounted on the clapper, and is provided with a set screw, bywhich. it can be adjustably set at any desired point along the length ofthe clapper. A gong is placed within the stroke of the clapper, and ismounted on a post 36, which is secured to the car by any suitable means.

3, storage battery is preferably used to provide the electric current tooperate the clapper apparatus, although if desired the current may betaken from the supply of motive current flowing through the trolley intothe car. The storage battery or several of them are placed at anyconvenient place on the car, and the circuit wires 37 and 88 areconnected to the positive and negative poles 39 and 4:0 respectively ofthe battery at one end, and are led to and connected at their oppositeends to the clapper apparatus, as follows: The circuit wire 87 connectswith the magnet coil 5, and the wire 38 is connected to the negativepole of the battery and extends to and connects with the crank 41 of theelectric current controller 42 of the car. A. circult wire 13 extendsfrom the magnet 6 to a ring, which I term the controller ring, which ispositioned on top of the controller casing. This controller 42, with itscrank 41, are elements that are in common use on electric street railwaycars, and they do not by themselves form a part of my invention, but arecotiperatively used and con nected with it. The controller ring -11,forms an element of Patent No. 86 1961 issued to me September 3d 1907.The cooperative arrangement of this ring, and the crank, and the circuitwires of the magnet and coil and gong ringing apparatus and the mannerof ringing the gong, are entirely different in my present invention, andits construction and ar angement is as follows:

Concentrically around the controller shaft, 1 secure to the top surfaceof the controller a ring-shaped box 15. This box is proided with arecess 46, in its peripheral edge, which fits around a stop post 17,which ounces is formed on the top of the controller casing. This box ismade of any suitable material, and incases and holds a non-conductingring 48, such as fiber or other suitable material, which is laid in it,and is secured in it against movement by a pair of cover rings 49, whichare secured to the edges of the box, and which are adapted to lap overthe edges of the box onto the fiber ring e 8, but are enough narrowerthan the width of the box to leave a circular space between them. Theend of the controller shaft is provided with a suitable crank receivingend portion, and the hub end 50 of the crank handle is provided with anaperture adapted to fit loosely on it. The under side of the handleportion of the crank is provided with a depending lug 51, which 1 term acontact lug, and which is made to fit loosely into the slot formedbetween the cover rings 49. This contact lug is also made long enough toextend down into the slot in contact with or in close proximity to thefiber ring, so that as the crank handle is swung around on thecontroller box in throwing on and off the current, the lower end of itsdepending lug will be either in bearing contact with the surface of thefiber ring or close to it. This ring is provided with a plurality ofcircuit contact points 52, which may be arranged in any desired orderand distance apart in its circumference, but which I preferably arrangein two groups A and B.

The group A of circuit contact points, commences on the starting side ofthe stop post 47, and I place the first contact point at a shortdistance from the stop lug, and the crank handle will contact with itwhen the said handle is moved far enough to start the car. The contactpoints are then placed at short equal distances apart for a distance ofabout one-half of the diameter of the fiber ring.

I have illustrated five contact points in Figs. 3, 4-, and 7, whichinclude the point for starting the car, and the point where it is undernearly but not quite full speed and the current is about half on.

The remainder of the group A, comprises three contact points, which arepositioned at short intervals, a long interval being left between thefifth and sixth points; consequently there is a portion of thenon-conductive ring that is preferably left blank and free from contactpoints, and this por tion represents that portion of the sweep of thecrank handle where the current is almost or about wholly thrown in bythe crank handle, and the car is under a high rate of speed but not atfull speed; and from just before the time the current is first turnedon, until the car has started up and attained fairly good speed, thegong only rings a single ring at each contact point of the group A asthe crank handle is swung around from the first one 53 adjacent to thestop post, then it passes over the space between the fifth. and sixthcontacts throwing on more current, after which it contacts successivelywith the last three contacts, each of which as the crank handle engagesit causes the gong to ring only once The group B, comprises two of thesecontacts, one on each side of the stop post, and this group B of contactpoints is used exclusively to ring the gong with a continuous successionof rings known as a vibratory ring, and when the crank handle is incontact with either one of these two contacts, it rings the gong with avibratory ring, and the crank handle is in constant engagement with themwhen the car is at rest or at full speed, whenever the motcrman throughcarelessness, neglects to hold the controller crank against the stoppost, as will be explained tn 1 ly hereinafter.

The group of disk contacts B of the ring is connected by a wire 54 tothe member 24:, of the make and break device, and the member 5 of themake and break device connects by a branch wire with the wire d3,connected with the magnet coil 6. Thus, when the crank handle is incontact with either one or the other of the two disks of the group C,the electric current passes from the negative pole of the battery to thecrank handle, and from the crank handle to one or the other of contactdisks of the said group B, and thence through the wire 5 lto the makeand break device, and thence through wire 55 to the magnet coils, andfrom the magnet coils through the wire 3? to the battery, thus forming acomplete circuit, the wire as, and the contact disks of the group A ofdisks being cut out of the circuit entirely, and when the crank handleis swung around onto the di ks of the two groups A and B, the circuit isformed from the battery through the wire 38 to the crank handle, andfrom the crank handle to and through any one of these disks and wire 4?;to the magnet coils, and from them through the wire 37 to the battery,and the wires 5% and 55, connecting the make and break device, and thetwo disks of the group B, with the magnet and battery, are out ofcircuit, The vibratory ringing action of the gong is given by a pin 56,that is secured to the armature in a position to engage the free end ofthe member 25, of the make and break device, as the armature contactswith the magnet poles. the end of the said member 25 being provided witha non-conducting strip 57, with which the pin contacts. The resilientmember 25, normally holds its'carbon tact, and breaks the circuit for afraction of a second as the spring 21 instantly draws the armature awayfrom the magnets, and the instant its pin 56 leaves the flexible member25, it springs against the fixed carbon contact and again closes thecircuit, and the magnets again attract the armature, thus causing theclapper to strike the gong with a continuous vibratory action, causingthe to ring continuously.

ihe contact points 52 of the non-conductive ring 48, preferably consistof semicircular shaped disks of any suitable conductive iaterial, whichextend loosely up through apertures 57, termed through the ring, andwhich arsecured to the ends of spring blades 58, the opposite ends ofwhich are secured to the bottom of the ring within a groove so that eachdisk is loosely supported in its respective aperture on a spring, thatallows it a resilient movement up and down in its aperture, and eachdisk is positioned so that a segment of its peripheral surface willproject above the top surface of the ring and lie in the path of the lugot' the controller crank. These contact points can be connected togetherin circuit by wires which are secured at the opposite ends from one tothe other oi these contact points around the ring, and at someconvenient point a circuit wire is connected at one end to one of theseconnecting wires, and extends to and is connected at its opposite end tothe magnet coils, as shown in Fig. 7. I preferably arrange these contactpoints, however, that one or more of them can be cut out of circuit andfrom each other, sothat the number of gong ringing contacts in the g uupA may be reduced if desired. In order to accomplish this, I provide eachcontact point with a switch, which consists of a swinging contactterminal spring blade 60. These spring blades are pivotally hinged atone end to the side of the ring 48, and wires 61 normally contact at oneend with them, while the opposite ends of these wires extend through thering and beneath the spring supported contact points 52, so that theywill be engaged by the said points, when the points are pressed down bythe tact lug of the controller crank, as nliown in Figs. 5 and 3. Thepivot screws the spring blades (it), also connect with a circuit wire62, which is fixed to the ring, ant which extends entirely around thering, each contact being connected to it through its switch terminalwire 61, and pivoted switch blade 60, and the wire 62 is connected bythe wire 43 with the magnet coils, the wire being pref rably extendeddown through a fiber bushing-not shownplaced in the top of thecontroller.

With either arrangement of connecting the gong ringing contacts in thecircuit, the circuit wire 43 is connected at one end to the circuit wire62 of the gong ringing disks, and at its opposite end to the magnetcoils, and the circuit wire 38 is connected at one end to the controllercrank, and is extended to and connected at its opoosite end lo thenegative pole of the battery, and from the magnet coils the wire 37extends to the positive pole of the battery, thus completing the circuitbetween the single stroke gong ringing disks and the controller crank.'ihese gong ringing disks extend far enough above the top of thenon-conductive ring to be engaged by the controller crank in successiveorder as it is swung around through its operative current switchingcircle, and as the contact lug of the controller crank engages eachcontact disk, its curved periphery permits itto spring down as the lugengages and is drawn over it, the gong ringing just once. And it it isdesired to cut out any of the disks, it is only necessary to remove theouter cap ring and swing the cut-out terminal spring blade on itspivotal center out of engagement with the wire 61.- While I haveillustrated this simple method of cutting out any of the disks, myinvention contemplates the use of any means for operatively cutting outthe disks.

On some street car systems, a checking device is used on the controller,and this device can be used in connection. with my invention. Itcomprises an automatic ratchet and pawl device that limits the movementof the controller crank to a series or" short movements, at the end ofeach of which the controller crank is stopped and has to be moved backslightly before it can be moved ahead again; thus compelling themotorman to turn his current into the resistance of the controller instep-by-step movements of the controller crank, and the resilientcontact disks are arranged in positions to be enga ed by the contact lugof the controller crank at the point where the controller crank isstopped by this motorneer device. The controller device is arranged toautomatically stop the controller crank directly over a circumferentialrow of radial lugs 63, that are forn'ied on the controller, to indicatethe proper step-by-step movement of the controller crank to turn thecurrent into the resistance elements of the controller, and as a guidefor the short stop movements of controller crank in turning the currentinto the resistance elements of the controller. The contact disks may beplaced at any desired distance apart, and arranged in any desiredmanner, and the radial lugs are suitably positioned relatively to thesaid disks. At a suitable point in the travel of the crank, in thepresent instance in line with the fifth contact point of the group A thecontroller is provided with the word Oil to indicate the current isflowing to the motors of tie car independently of the controllersresistance. Ithus provide means by which the motorman may know when heis running his car on aresistance current, as the gong will always ringonce when the controller crank is over any of the resistance guide lugs.Motormen are apt to run their cars on the resistance current, and by sodoing soon burn out the resistance coils or elements of the controller,and one of the essential elements of my invention is to arrange thegroup A of contact disks so that the gong always rings as the crankhandle contacts with each of the first five contact points when the caris running on the resistance current, and also when it en gages each ofthe remaining contacts when the controller is off from the resistanceand the motors are in series.

My automatic gong ringing device is also adapted to compel the motormanto either remove the controller crank from the controllers switch shaftwhen his car is stand-.

ing still, or hold it continuously against the stop post or submit to acontinuous ringing of the alarm gong, and also to either hold thecontroller crank against the stop post when his car is running at fullspeed or submit to a continuous ringing of the gong; consequently, oneof its objects is to compel motormen to attend strictly to the properoperation of the controller crank. There are several ways in which thisfeature of my invention can be accomplished, but I preferably carry outthis feature of my invention in the manner described in my former patentabove referred to, which is as follows:

To the center of the stop post I secure the lower ends of a pair ofblade springs 64, the free ends of which are arranged to be engaged bythe controller crank when it is within a short distance of the stop postso that the springs will hold the controller crank far enough away fromeither side of the stop post to bring its contact lug in engagement withthe adjacent contact disk on either side of the stop post, and thuscause the gong to ring. So when the car is stand ing he must either holdthe controller crank continuously against the stop post and against theresilient pressure of the springs 6a, where it would be out of contactwith the contact disk, or submit to a continuous ringing of the gong,and in case he leaves the controller he must remove the controller crankfrom the controller shaft or submit to a continuous ringing of the gong,and when the car is running at full speed he must either hold the switchcrank up against the stop post continuously against the pressure of thesprings 64 or submit to a con-J tinuous ringing of the gong. The springs64: curve out laterally at their free ends, so as to engage thecontroller crank before it abuts against the stop post, as clearly shownin Fig. 3.

The operation of my invention as applied to street railway car service,is as follows: The motorman on taking charge of the con troller puts thecontroller crank on the controller sha..t, and to prevent the vibratoryringing of the gong holds the crank against the stop post, and off ofthe adjacent contact disk. Upon receiving the signal to go ahead hemoves the crank to the contact disk 53, where the gong rings once, andthen continues to move it by a succession of short sharp movements tothe cut-ofi' indicating point, the gong ringing once at each disk of thegroup A. until the crank handle has rea :hed the cut-off point. The carwhich was started and got under headway by current flowing through theresistance elements of the controller is when the crank reaches thecut-off running by current flowing di rectly from the trolley to themotors which at this point are connected in series. The motorman thenthrows the crank around to the stop post, and this portion of the cranksmovement actuates the controller to throw the motors in parallel runningrelation, and the gong rings once as the crank passes over eachcontactdisk until it reaches the disk 65, of the group B, when it willring a vibratory ring if stopped on the disk, and will continue to ringuntil the crank handle is moved off from this disk against the post andis pressed against the stop post, and he must hold the crank against thepost by applying a slight but firm constant pressure against it in orderto prevent its engaging this disk and ringing constantly, as the instanthe releases the pressure on the crank the spring (Set will move it backin contact with the disk and the gong will commence to ring.Consequently, when running and when occasion arises to ring the gongwith a vibratory ring, he relaxes the pressure on the crank enough toallow the spring to move it away from the postin contact with theadjacent disk, and then presses it against the stop postwhen he wants itto stop, and when he wants to stop the car he makes a quick backwardsweeping stroke with the crank, until he strikes the opposite side ofthe stop post again, at which point he must again hold the crank againstthe stop post or remove the crank, if he wishes to prevent the gong fromringing, or he can keep the gong ringing until he is ready to start byrelaxing his pressure on the crank.

My gong ringing clapper apparatus is adapted also for fire-alarm trucksand wagons, and when used for that service a foot button 66 can beinserted in a sleeve 67, which is adapted to be placed in the platformfloor of the seat within easy reach of the feet of the driver. The stem68 of the button and the button are reciprocally mounted in the sleeve.A terminal contact block 69 is placed in the bottom of the sleeve, and aspring 70 is placed on the stem and arranged to normally hold the lowerend of the stem out of engagement with the contact block 69, and thevibrator wire 5% is connected to this contact block, while the batterywire 38 is connected to the sleeve; consequently when the driver wantsto ring vibrating ring of the bell, he places his foot on the button andpresses it down until the stem strikes against and rests on the con tactblock 69, which closes the circuit through the carbon vibrating contactpoints and the coils and battery, the single bell ringing stroke wirebeing entirely out of the circuit. This single bell ringing wire 43 isalso extended to the inside of the bore of the sleeve, and is providedwith a contact terminal portion 71, and the stem of the foot push buttonis provided with a projecting contact lug 72, that is positioned on itto engage the terminal contact portion of the single gong stroke wirewhen the foot button and its stem are pressed downward, but a portion ofthe movement of their full downward stroke. Then if the driver desiresto strike a single stroke of the gong he presses his foot on the buttonand presses it down until the gong rings, which will be when the contact1 g 72 on the stem engages the terminal contact 71 of the wire Theelectric circuit is then through the battery to the sleeve and foot pushbutton and stem to and through the single stroke wire 43 to the magnetcoils back of the battery, which attract the magnet, causing the clapperto strike the gong, the vibratory bell striking wire and the carbonvibrators being entirely out out of this circuit. The driver must raisehis feet after each stroke oi the gong and again push down every time hewants to strike a single stroke of the gong, but when he wants to ring acontinuous vibratory bell he pushes the foot button down and holds itdown and the gong will ring continuously as long as he holds the footpush button down.

My invention is also adapted to be used for any alarm bell system whereeither a single or vibratory alarm is required, and while Ihave shown itadapted to be operated by a swinging lever switch system for streetrailway car service, and by a push button switch system for the alarmservice, my invention contemplates the use of it with any type ofswitch, and for all purposes where a strong reliable loud gong strikingapparatus is required.
